Title:
POLYTHIOL COMPOSITION, OPTICAL POLYMERIZABLE COMPOSITION, AND OPTICAL PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/065802
Kind Code:
A1
Abstract:
A polythiol composition according to exemplified embodiments comprises a first polythiol compound, and a second polythiol compound having a larger molecular weight than the first polythiol compound and having a number of functional groups that is greater than or equal to the number of functional groups of the first polythiol compound. The amount of the second polythiol compound is 500-20,000 ppm on the basis of the weight of the first polythiol compound. The reaction rate of an isocyanate-based compound is controlled by the second polythiol compound so that striae are prevented and the mechanical properties of an optical product can be improved.
